No chance. That's a hard timeout enforced by the PPP peer.

They time out after 24 hours. Additionaly, the connection sometimes 
breaks at random times (but rarely), probably because of router reboots
or whatever things they do when they have problems.

That's not realy a problem, IMHO.

Put everything you need to do on ip assignement into your ip-up script (like
modifying the remote nameserver, reestablishing tunnels, ...)

Then force an imediate redial when the PPP connection drops (this depends on
the PPP stuff you use), putting

  ( sleep 30; ping -o -c 5 ftp.somewhere.else ) &

into your ip-down script should always work. With isp0 or similar interfaces
(like NetBSD's pppoe0) just don't set the link1 flag on the isp interface.
